NON-SKID nnvro'n.

Specification of Letters Patent.

Application filed February 16, 1914. Serial No. 818,923.

To all whom it may concern Be it known that I, JOSEPH Sanns, a subject of the Emperor of Austria-Hungary, residing at Filbert, in the county of Mo- Dowell and State of Vest Virginia, have invented certain new and useful Improvements in Non-Skid Devices, of which the following is a specification.

This invention relates to certain new and useful improvements in non-skid device.

An object of the present invention is the provision of a structure easily and cheaply manufactured from sheet material for positioning circumferentially upon the tires of, wheels, such as automobile wheels, to posiboth a. side slipping or skidding of the vehicle as well as affording a positive ground contact for traction puroses.

A further object is to provide a single metallic element in a single length or strip for lacing upon an automobile tire and, fitting the same upon an inflation of the tire while having a positive tread grip both longitudinally and transversely arranged.

A still further object is to provide a nonskid member of a circumferential base strip with a bent strip mounted thereon having a plurality of longitudinal ribs and, the latter having bent side strips mounted: with transverse ribs centrally positioned upon either side of each longitudinal rib portion.

With these general objects in view. and others that will appear as the nature of the invention is better understood the same 0011- sists in the novel construction and combination of parts as will be hereinafter more fully described and pointed out in the ap pended claims.

In the drawings forming a part of this application and in which like numerals of reference designate corresponding parts throughout the several. views .Figure 1 is a side elevation of a pneumatic tire having the device mounted thereon. Fig.2 is a detail view of the rib formation thereof. Fig. 3 is a central vertical longitudinal sectional view of the device in position, and with the'tire shown in dotted lines. Fig. i is a plan. view of a section of the device detached, and

partly broken away and Fig. 5 is a trans i 5e sectional iew upon line 5-5 of Fig. 1.

iteferring more in detail to the drawings,

the present invention is herein illustrated, being mounted upon the pneumatic tire 10 which in turn, is positioned in the clencher rim 11 upon the felly 12.

The non-slrid member adapted to be se cured to the tread-portion of the tire comprises the base plate 13 which is preferably made of sheet metal in a strip of sufficient length to substantially encircle the tire and is positioned thereon when the tire is partly deflated, the ends of said member being secured together as desired and preferably by the lacing 14, while the side edges of said I strip are incised at regular intervals form ing side flaps 15 engaging the tire and allowing the base strip to readily assume Zthe curved hoop formation. Co-extensive with the length of said base strip and seicured to the outer face thereof is the rib plate 16 having the central longitudinal 'rib 17 which is formed therein by a folding of' the strip along its longitudinal central line as best shown in Fig. 2, and after which the rib 17 is transversely cut at regular in- Patented Jun- 16, 1914.

tervals forming the separate longitudinal rib portions 17. Upon each side of the rib 17 there is mounted a rib strip 18 which is folded at regular intervals into ribs 19 of double thickness, the said ribs 19 thereby lying transversely of the member and in alinement upon opposite sides of and substantially. mid-way of the :length' of each of the longitudinal rib portions 17. The

inner faces of' the transverse ribs 19/ are slightly inclined at 20 when the device is in its straightened condition which provides -the same substantially parallelto the longitudinal rib 17 when placed upon the tire, while the flaps 15 being separated when not in use are brought substantially together when the device is placed in hoop form and the longitudinal rib sections 17 are slightly separated by this action when the device is placed upon the tire.

Placing the base strip upon the tire when partly deflated, then securing the lacing 14 and again re infiating the tire, positions the non-skid firmly upon the latter and the securing straps 21 of leather, rubber or any other material desired are provided at regular intervals and secured by screws, rivets, hooks, or other fastening means 21 to opposite flaps 15 of the base strip.

I said base strip, and

rial from which the same prising a base strip,

device When not in use is in the form of a strip member which may be easily stored away or carried in the automobile, preferably coiled up in a small space, being preferably formed entirely of thin spring metal, and Which'in the manner scribed, is readily attached to the periphery of the tire and then affords a most positive traction surface for the entire tire tread.

While the forms of shown and described that the complete the invention herein as Well as the mateis constructed, is believed to be preferable, it is nevertheless to be understood that minor changes may be made inthe form, proportion and details of construction Without departing from the spirit and scope of the invention.

What I claim as new is zl. A device of the class described comprising a base strip, a rib plate mounted thereon and bent with a central longitudinal rib, rib strips secured to the outer face of said rib plate and bent into spaced-apart transverse ribs.

2. A device of the class described comprising a base strip, a rib plate having integral bent longitudinal rib members thereon, and rib strips positioned at opposite sides of said rib member and upon said rib plate and integrally bent into transverse ribs.

3. A device of the. class described coma rib plate bent with an integral longitudinal rib and mounted upon said rib being divided into sections, rib strips mounted upon the rib plate at each side of the rib thereof and bent upon themselves forming transverse ribs arranged in alinement and substantially 1nto equal sections,

' of said longitudinal mid-Way of the lengths .of the longitudinal rib sections.

4. A device of the class described comprising a base plate adapted for encircling a tire and having slotted edge portions forming si'de flaps, lacings for uniting the free ends of said strip, a rib plate co-extensive in length with said base strip and centrally folded at substantially right angles to its side portions into a longitudinal rib divided. separate rib strips mounted upon the rib plate at opposite sides tially perpendicular to the main portions of the rib strip and forming transverse ribs in substantial alinement at opposite sides of the middle point'of the longitudinal rib sections. c

5. A device of the class described comtprising a metallic base strip having side aps, a rib plate flatly engaging said base strip and centrally folded upon itself into a plurality of longitudinal rib sections, rib strips upon opposite sides of said sections secured to the rib plate and integrally. bent into transverse rib sections positioned centrally in alinement at opposite sides of the longitudinal rib sections, thednner faces of the transverse rib sections being substantially parallel to the adjacent faces ofthe longitudinal rib sections when in posit-ion upon a tire, and strap members secured between opposite ones of said flaps. In testimony whereof I in presence of two witnesses.
